- Performance Indicators
All of the indicators are based on data collated for concrete production.
In addition, some indicators report on the additional effects of including a contribution from the reinforcement steel sector, based on data provided by BAR. This is shown under the heading ‘concrete + reinforcement’.
More details of the background and methodology for these indicators can be obtained from the publication Concrete Industry Guidance on Performance Indicators.
The concrete industry makes a significant contribution to biodiversity and nature conservation through the management and restoration of sites of mineral extraction.
The indicator for production CO2 is carbon intensity or CO2/tonne of concrete produced. Data from the energy use of concrete production and a proportional contribution from constituent materials are converted to carbon emissions using factors published by DEFRA with an adjustment for the process carbon emissions from cement.
Our indicator relating to emissions excluding CO2 reports the number of convictions for emissions to air and water within the industry per annum.
Having a skilled, competent and informed workforce is essential for the industry to remain competitive, safe and capable of meeting the objectives of the concrete industry strategy.
Reducing the carbon dioxide emissions associated with the production of concrete and its constituent materials can be achieved by improving energy efficiency and reducing consumption.
Controlling and managing the environmental impacts of procuring materials and manufacturing products is an essential requirement for sustainable development.
Health and safety of its employees is a key focus of the concrete industry strategy. Two indicators are used to report performance and are established benchmarks of health and safety.
It is often the case that concrete supply chain production sites have close links with the local communities through the employment of local people and the use of local materials.
Product consistency, performance and being fit for purpose are crucial to sustainability and ensuring that materials are not rejected or potentially wasted, which is costly both economically and environmentally.
There are significant volumes of by-product materials such as ground granulated blastfurnace slag (GGBS) and fly ash that can act as part of the cementitious binder in concrete. These materials have a lower embodied carbon than cement and can also influence the appearance and performance of concrete.
The concrete industry was the first industry to link its sustainable construction strategy to BES 6001 and has produced the publication 'Specifying Sustainable Concrete' to support the implementation of the standard.
Concrete and its constiuent materials are locally produced in the UK. In 2016 the average delivery distance for all concrete was 46 km (or 28.8 miles). The average delivery distance for all raw materials for concrete was 72 km.
The concrete industry is a net user of waste, consuming 99 times more recovered and waste materials than the waste it sent to landfill.
Water is an essential ingredient for the hydration of cement and is an important resource for concrete and its materials supply chain.
